Ron Guidry calls his new pitch the "dead fish." It's a little like a screwball, and it has him off to a 2-0 start for the New York Yankees in 1986. And the Yankees, as a team, are off to their best start in 11 years.

With seven innings from Guidry and a two-run single from Don Mattingly, the Yankees defeated the Milwaukee Brewers, 3-2, yesterday in New York. Dave Righetti struck out the side in the ninth for his third save. The Yankees have won four in a row and five of their first six games, equaling their 1976 start.

"I haven't thrown my best fastball yet," said Guidry. "I probably could. It'll come around later, but I'm not really trying to throw it yet."

The Yankees were outhit by 11-3 and scored all their runs in the third inning on Willie Randolph's RBI double and Mattingly's single.

*Red Sox 12, White Sox 2: In Chicago, Wade Boggs had three singles and four RBI as Boston got 16 hits in winning easily. Jim Rice homered and had three RBI and Bill Buckner and Dwight Evans each had two RBI.

Boston starter Tim Lollar allowed two hits and one run in six innings, but issued seven walks.

Joe Cowley was knocked out in the third inning when Boston sent 10 men to the plate and scored five runs.

*Indians 8, Tigers 2: Scott Bailes earned his first major league victory with 5 1/3 scoreless innings of two-hit relief and Andre Thornton's homer highlighted a five-run first inning as Cleveland won at home. The Indians had 19 hits.

Bailes, 24, yielded singles by Kirk Gibson in the seventh inning and Larry Herndon in the eighth in relief of starter Don Schulze.

Indians rookie catcher Andy Allanson went three for four, giving him 10 hits in 20 at bats.

*Royals 7, Blue Jays 4: Frank White and Hal McRae jumped on relief pitcher Dennis Lamp with RBI singles in the fifth inning to carry Kansas City to victory at home.

Willie Wilson and George Brett hit consecutive home runs in the third inning and Steve Balboni homered in the fourth, all of them off Dave Stieb and all with the bases empty, as the Royals took two of three games in a rematch of last year's AL division champions.

Bud Black (1-1) got the victory. Steve Farr pitched four innings for the save.

*Mariners 4, Twins 2: In Minneapolis, Danny Tartabull broke an eighth-inning tie with a two-run homer, his third extra-base hit of the game, to lift Seattle to victory.

Winner Mike Moore (1-0) pitched a six-hitter, striking out five and walking one. Loser Mike Smithson (1-1) went the distance and tied his career high with nine strikeouts.

Ken Phelps, batting for Steve Yeager in the eighth inning for Seattle, walked and Tartabull, who also had two doubles, hit his second home run of the season, a 410-footer over the left field fence. Tartabull, Seattle's leadoff hitter, hit 43 homers in Class AAA last season.

*A's 11, Angels 7: Rookie Jose Canseco drove in five runs with a single and his second home run -- the only two Oakland has this season -- as the A's won at home.
